Green Hills Software Announces Multicore TimeMachine Trace Tools for MIPS and Renesas Microcontrollers

For SoC designers, multicore TimeMachine is a powerful tool to assist with pre-tape-out chip verification, reducing risk, time-to-market, and time to accelerate silicon sales. TimeMachine’s advanced scripting capabilities allow for automated testing on virtual platforms.

“Imagination is delighted that our long-time partner Green Hills is making its multicore TimeMachine tools available for MIPS CPUs. Multicore and multi-threaded MIPS cores provide high-performance, efficient processing across a wide range of embedded and consumer products. With multicore TimeMachine, developers creating software for these processors have a new level of visibility and control, with the ability to debug, optimize, and test code in powerful new ways,” said Tony King-Smith, EVP of marketing, Imagination Technologies, which recently acquired MIPS Technologies and with it the industry-standard MIPS microprocessor architecture.

For software developers, multicore TimeMachine enables developers to visualize, replay, and debug their software’s execution backward in time across multiple cores within an SoC. The TimeMachine suite enables firmware engineers to quickly find bugs and inefficiencies in multicore systems. As part of the Green Hills Software MULTI IDE, this capability enables multicore bugs to be easily and quickly eliminated. Without the trace-based visibility of TimeMachine, the complex interactions between multiple heterogeneous cores are difficult to see, resulting in long turn-around times on software defects.

The TimeMachine debugger allows the user to synchronously step forward and backward on all cores, to set software and hardware breakpoints and to run forwards or backwards, so all cores synchronously stop upon hitting the breakpoint. As a result the user can see what all cores are doing before and upon hitting those breakpoints. Developers can optimize their program through profiling information derived non-intrusively from gigabytes of trace data. Beyond debugging, confidence for completeness in testing can be obtained from code coverage data also derived non-intrusively from the trace data.

“For the past decade, TimeMachine has been the premier tool in the embedded industry for tracking down the most difficult bugs - those intermittent and hard to reproduce problems that so often cause software to be late or buggy. Those difficult bugs have only become more complicated over the years as software is running across multiple cores on extremely complex devices. Multicore TimeMachine allows the execution of all cores on the SoC to be replayed repeatedly, and for the first time giving developers the control and visibility required to efficiently solve the most difficult problems,” commented Tim Reed, vice president of Advanced Products, Green Hills Software.
